I want to fit an extractor fan in my bathroom. The fan I would like to
fit needs three electrical connections: live, switched live and neutral.
Can I just connect to the existing connections in the lighting
circuit or do I need an additional switch and fuses? Is there a better
way to do this?

Thanks for any advice.

Gareth.

You can connect to the lighting circuit (and this is the preferred way
if you are using a run-on fan controlled by a light switch).

You *may* need additional fusing - see the fan data sheet. Some need
protection at 3A, some are ok at 6A, and some lighting circuits are
protected at 10A.

You will need a 3 pole isolation switch to enable the fan to be fully
turned off for servicing / cleaning. This can be either a wall mounted
jobby (if placed in zone 2 or outside), or a pull string type. If the
isolator is in a separate room from the fan then it ought to be a type
that can be locked off (although this requirements is often ignored in
practice it seems).

Thanks. The fan needs a 3A fuse and my lighting is 5A so I need fuses.

turned off for servicing / cleaning. This can be either a wall mounted
jobby (if placed in zone 2 or outside), or a pull string type. If the

Thanks for your reply.

Yes, I think that's what I need.

Thanks.
